Definitions

  • the present invention relates to the technical field of land motor vehicles and, more particularly, a device for assembling a bumper of such a vehicle on the structure of the latter.
  • a land motor vehicle is made up, in a conventional manner, of a shell or structure which is intended to receive bodywork elements such as for example a grille, fenders and front and rear bumpers, as well as a front facade which is often fitted with equipment, in particular with optical units, an air-blower motor-fan unit, a radiator, an air filter, an audible warning device and which also contributes to the connection and the stiffening of the front part of the hull or structure which, usually, is extended by two lateral beams which form a stretcher and which in particular serve as a cradle for receiving a powerplant and all that is associated with it.
  • bodywork elements such as for example a grille, fenders and front and rear bumpers, as well as a front facade which is often fitted with equipment, in particular with optical units, an air-blower motor-fan unit, a radiator, an air filter, an audible warning device and which also contributes to the connection and the stiffening of the front part of the hull or structure which, usually, is extended by
  • the bumpers of contemporary vehicles essentially comprise a transverse beam and an exterior covering or skin between which a lining is optionally placed.
  • the beam usually has mechanical properties which allow it to deform elastically or even in an irreversible way to contribute to the absorption and dissipation of the energy which results from shocks qualified as "large” and which can occur when the vehicle travels at a speed greater than approximately 4 km / h.
  • the purpose of the coating or skin is essentially to give the vehicle its aesthetic appearance and its particular aerodynamic qualities and possibly, contributes to absorbing the energy of the shocks qualified as "small” such than those that can occur during traffic at a speed not exceeding approximately 4 km / h, for example during storage maneuvers on a parking lot.
  • Such a coating or skin is currently preferably made from synthetic materials such as polypropylene or an epoxy resin reinforced by a glass fiber fabric in particular. As is known, depending on the materials used, such a coating or skin is obtained by injection, stamping or even extrusion / blowing manufacturing techniques.
  • the beam of such a bumper is joined to the shell or structure using appropriate fixing means, and the covering or skin is itself secured using assembly bridges or the like arranged in suitable places, for example near the sides of the bumper and at the base thereof.
  • the coating or skin of the bumper Due to the manufacturing tolerances of each of the constituents to be joined, as well as the mounting and fixing tolerances, it follows that during its assembly, the coating or skin of the bumper has positional deviations both longitudinally and transversely or even vertically with respect to its theoretical or nominal position. It follows that if one mounted as is, in such a situation, a bumper covering or skin, some of its contour lines would sometimes poorly connect with the corresponding lines of other components such as the wings or optical units and the grille, in particular.
  • the constituents to be joined are such that at least some of them are endowed with degrees of freedom, between certain limits, which make it possible during the final phase of the assembly to make up for the differences in position resulting from the manufacturing and mounting tolerances.
  • the object of the invention is to remedy this type of drawback.
  • the invention relates to a device for assembling a bumper of a land motor vehicle on the structure of the latter and which has the general configuration of a polygonal deformable support bracket which comprises faces and at least four vertices.
  • a device is disclosed in document GB-A-2 022 212.
  • the device further comprises articulations obtained by local thinning of material of each vertex relative to the faces which frame it.
  • Land motor vehicles being well known in the art as well as their structure or shell and bumper, we will only describe in what follows that relates directly or indirectly to the invention. For the rest, the skilled person in the technical sector considered will use the current conventional techniques at his disposal to deal with the particular problems with which he is confronted.
  • indications such as up, down, lateral, transverse, vertical, front, rear, anterior, posterior in particular are identified with respect to the traditional axes of orientation of a vehicle.
  • the assembly device according to the invention is intended to assemble a bumper on a traditional hull or structure S of a vehicle.
  • a hull or structure S is usually extended by beams L which form a stretcher for a cradle intended to receive a powerplant with a front axle, its suspension and its steering in particular.
  • Such a hull or structure receives bodywork elements such as a radiator grille D, wings A and a bumper 10 which are usually joined to the longitudinal members L by means of fixing means possibly with the interposition of energy-absorbing buffers. .
  • a front panel F most often equipped with optical units O, a fan motor unit P blower, a radiator, an air filter E and, if necessary, an audible warning device K, is also fitted to the front part of the hull or structure S and often contributes to ensuring its stiffening by providing the connection of the two opposite sides.
  • a bumper 10 usually consists of an interior transverse beam (not shown) and a coating 11 or skin, exterior with, if necessary, interposition between beam and coating of a lining contributing to ensuring the absorption of energy in the event of shocks.
  • the coating or skin 11 is provided with at least one opening 111 formed in this coating and located at a suitable location for the reasons which will be understood later.
  • This coating or skin 11 also comprises at least one bridge 112 for its assembly and, optionally, at least one side tab 113 whose role will appear later.
  • a device 20 for assembling a bumper of a land motor vehicle on the structure or shell of the latter, according to the invention, has a general configuration as a polygonal deformable stirrup-support.
  • This stirrup comprises faces 21 and at least four vertices 22 which are joined by articulations 23.
  • this support bracket is essentially in the manner of a bridge 211 with two arms 212 which are located opposite, and two flanges 213 preferably practically parallel to the bridge 211 and directed in directions opposite, as shown.
  • One of the ends of each of the branches 211 is joined to the bridge 211 by a joint 23 and the two flanges 213 are each joined to the other of the ends of one of the branches 212 by another joint 23.
  • the support bracket according to the invention therefore has, in cross section, the appearance of a more or less divergent U if necessary.
  • the joints 23 are obtained by a local thinning of material from the top 22 relative to the faces 21 which surround it, as is clearly shown in the figures of the drawing.
  • the stirrup is pierced with an orifice 2110, for example oblong, as illustrated, placed on the bridge 211.
  • a device according to the invention is carried by this coating or skin of the bumper so that the support bracket protrudes on one side of the coating or skin of the bumper and this preferably plumb with an opening.
  • the support bracket can deform when subjected to a stress which has a component located in a plane perpendicular to the joints and parallel to the bridge.
  • the support bracket is reversible, that is to say that it can cross the aperture so as to protrude from the other side of the covering, opposite to that on which it was initially located, for example at the end of the manufacturing operations.
  • the support bracket is made of a synthetic material which is for example fixed to the covering by means of its edges, in particular by ultrasonic welding when the covering is itself made of a synthetic material, or even in one piece with the latter.
  • the support bracket and the covering can be made of the same material or of different materials.
  • the support bracket can also be fixed to the covering by any other suitable technique, for example, screwing, riveting, gluing, etc.
  • a device according to the invention is used at least at the base of the coating and at least on one side of the latter as illustrated in particular in FIG. 1.
  • the assembly device (s) located at the base of the covering which makes it possible to align in one direction or the other in the transverse direction Y. Such alignment can be done independently of fixing this covering with respect to its other mounting points. It will also be observed that the reversibility by inversion of the stirrup assembly device also allows variations to compensate for deviations in the vertical direction Z.
  • stirrup-support assembly device can also be used for fixing other components such as, for example, protective screens or the like under the engine.
  • the device according to the invention brings to the assembly, it offers a significant advantage in the event of impacts near the middle zone of the bumper since the assembly at the level of the wing has the particularity of being movable according to the longitudinal axis X and not to deform the wing or to cause the attachment to rupture.
